Ghost has gone to prison, been a suspect and person of interest in multiple felonies, the victim of several crime-related homicides involving people in his circle, has had his club shut down for murders and suspicion of drugs being run through his club, and has had high-profile witnesses merked that could have put him away.
There's no way in fukk he would ever be an asset to anybody's political campaign, and Tate and 50 other politicians wouldn't be caught dead holding a function at Truth, which is ground zero for all of Ghost's fukkery and the place he got arrested
And his crib got shot the fukk up just last episode in a way that only happens if you're involved with organized crime or terrorist activity. I'm sure several of those politicians stay in his building or down the street. They wouldn't be caught dead at that function.
I don't get why they veer so heavily from the origin of his name "Ghost". He should be making political ties, but having this huge need to be so visible with it goes against common sense and the basis of his character as a whole.
